How to calculate Standard Deviation?

Standard deviation is a statistical measure that tells us how spread out a set of data is. A low standard deviation means the data points tend to be close to the mean, while a high standard deviation indicates that the data points are spread out over a wider range.

Here’s a step-by-step guide to calculate standard deviation:

1. Calculate the mean:
   Add up all the data points.
   Divide the sum by the number of data points.
   
2. Calculate the deviation of each data point from the mean:
   Subtract the mean from each data point.
   
3. Square each deviation:
   Square each deviation calculated in step 2.
   
4. Calculate the variance:
   Add up all the squared deviations.
   Divide the sum by the number of data points minus 1 (for sample standard deviation) or by the number of data points (for population standard deviation).
   
5. Calculate the standard deviation:
   Take the square root of the variance.
